• Maintain a comprehensive OT Asset Register covering all hardware firmware software and network connectivity. Flag all shadow or unmanaged devices.
• Review and document the IT/OT network architecture producing topology diagrams that capture OT-to-IT connectivity remote access paths vendor interfaces and boundary crossing points each risk-rated.
• Map operational data flows between OT and IT systems to identify lateral attack paths including where meteorological process data crosses into less-secure corporate network segments.
• Maintain the OT Asset Register and IT/OT Network Architecture Map as the foundational security baseline for all vulnerability assessments risk management and incident response activities

Security Operations & Monitoring

• Monitor and defend operational technology (OT) supporting meteorological systems including weather radar networks (e.g. Doppler Weather Radar S/C Bands) satellite ground stations upper-air sounding systems and automated weather observation systems (AWOS).
• Operate and maintain security information and event management (SIEM) tools to detect anomalies across hybrid IT/OT environments.
• Work closely with the Agencys CISO to manage and deploy critical patches and others security incidents.
